SPECIFIGATION forming part of Letters Patent No.244,620, dated July 19, 1881, Application filed January 17,1880.-

To all whom it may concern;

Be it known that we, J on: KLASSEN and NIo oLAUs SOHWARZ, of La Porte, in the county of La Porte, State of Indiana, have in- 1 vented certain new and useful Improvements in Fanning-Mills; and we do hereby declare that the following isa full, clear, and exact description thereof, reference being had to the accompanying drawings, making apart of this specification, in which- Figurelis a perspective view of ourimproved machine from thegjrear sideiffitFig. 2 isla like view of the front end of the same, the hinged drum being swung to one side, so as to afford access to the fan. Fig. 3 is a perspective view of the rear upper portion of said machine, the

, hinged hopper being turned upward and forward. Fig. 4 is a vertical central section of said machine upon alongitudinal line; and Fig. 5 is a transverse vertical section.

Letters of like name and kind refer to like parts in each of the figures.

The design of our invention is to increase the efliciency of fanning-mills, and to render the same .more convenient to operate and: repair; and to'this end it consists, principally, in a fanning-mill provided with a drum hinged at one end to or upon the frame of the machine, and

' having air-openings in each end thereof capable of being closed by suitable slides, the side boards of the machine being provided with other air-openings capable of being closed by suitable slides and partitions of peculiar construction that partly incl'ose the fan and admit air at the from side of the fan, substantially as and for the purpose hereinafter specified.

It consists, further, in the means employed for vibrating the lower sieve, substantially as and for the purpose hereinafter set forth.

In the annexed drawings, A and A represent fourposts which are arranged vertioallyin pairs, and are connected together by means of crossbeams B and B and side boards, 0 and O, to form the frame of our machine.

J ournaled within suitable bearin gs upon the outer face of the postsA and A, at one end ofthe frame, is a horizontal shaft, D, which is provided with radial arms d, that are arranged in pairs, and each pair connected together by means of a thin board, 11, the whole forming a fan of usual form.

The fan described is rotated by means of a shaft, E, that is journaled above and in front of the shaft D, and is provided upon its outer end with an operating-crank, e, and at its inner pinion, 01 that is secured upon said shaft D. The fan is inclosed upon its outer side by means and is hinged at one end to or upon the outer face of one of the posts A, while at its opposite end is'provided a button, f, or other fastening, by which said end is secured in place. By means of such connection with the frame said drum may be swung outward and to one side, so as to uncover said fan and permit of the reof the fan is partly incl'osed by means of a partition, Gr,which extends from the upper edge of the drum F, forward and downward in a curve, nearly to the level of the shaft D, and thence for a short distance forward and upward,while below said fan is a second partition, H, which extends from'the posts A forward andiupward about one-half the length of the frame, and thence for a short distance forward and downward. The arrangement described furnishes through which air may pass forward into the machine. An air-supplyis admitted to said cas ing through openings f in each end of the drum F, and other openings, 0, in the side boards, (3, which openings are wholly or partly closed, as desired, by means of slides f and 0. respectively.

Withi'n the front upper portionof the frame boards, I, that, have the wedge shape shown in Fig. 4, a bottom board, i, that is secured to and extends between the lower edge of said parts, a cross-board, i, that extends between the upper edges, at the rear ends of 'said side boards, and a cross-bar, 6 which is secured upon and extends between the upper edges, near the front ends of the latter. The shoe described is provided within its side boards, I, with grooves i for the reception, in the usual manner, of screens or sieves K and K, and the whole is suspended within the frame of the machine by means of two hangers, L, one of 100 which is pivoted at its lower end to or upon each side of said shoe, near its front end, and

of a drum, F, that has a semi-cylindrical form,

end with a gear-wheel,e,wh1ch meshes with a pair or removal of the same. The innerside an openin g at the front side of the famcasing, I

is placed a shoe which is composed of two side at its upper end is hooked into an eye or staple, I, that projects downward from the cross-bar B, and a bar, M, that is rigidly attached to the center of the cross-board i, and from thence projects upward and forward into a horizontal slot, 1), that is provided within the rear upper cross-bar, B, where said bar is pivoted by means of a pin,m, that passes through its end and through said cross-bar. The shoe thus constructed, with the frame, is free to vibrate laterally, and maybe easily removed from or replaced within said frame, the hangers L and pivotal bar M being readily and quickly disconnected, so as to free said shoe. The shoe is vibrated laterally at its rear end by means of a three-armed rocker, N, which is pivoted or journaled upon the front end of the frame, opposite the center, vertically, of said shoe, arod, 0, pivoted at one end upon the side of the latter and at its opposite end to the central rearward-extendin g arm of said rocker, a disk, 1?, secured upon and revolving with the end of the\shaft D, and a rod, Q, that is pivoted at one end to the outer arm of said rocker and at its opposite end to said disk, at one side of its center, said parts operating in the usual manner. The arms of said rocker and said disk are each providcdwith a number of holes for the reception of the connecting ends of the rods 0 and Q, which holes are placed at diflerent distances from the pivotal center, and by changing said rods from one set of openings to another the amount of motion of the shoe may be increased or diminished at will.

In order that the cheat may be more thoroughly separated from the grain, the lower end of the lower sieve rests upon and is supported by means of a triangular bar, R, which is journaled within the side boards,I, at the lower inner corner of the shoe, and at one end is provided with a crank-arm, 1', that extends upward and has its upper end connected, by means of a rod, S, with the inner arm of the rocker N. As the said rocker is vibrated horizontally by means of the rod Q and disk P said bar R is caused to vibrate so as to cause its corners to alternately strike against and raise said sieve.

Below the shoe is placed the usual box or drawer, T, for the reception of cheat, while upon a line with the bottom board, 1', is the per is hinged to said frame at its rear end, and

is capable of being raised to the position shown in Fig. 3, so as to uncover the shoe and permit the same to be regulated, repaired, or removed, when necessary.

Within the front side of the hopper Uis the usual slide, u, for regulating the passage of grain to the shoe, which slide has its side edges contained" in grooves and is held in place by means of a flat spring, V, that extends across its lower side at the front edge of said hopper, and at its longitudinal center bears upon a bar, u, which extends lengthwise of the lower side of said slide. The location of the spring V below the slide to leaves the upper side of said slide and of the hopper free of all obstruction, and is of material advantage in the operation of the machine.

Having thus fully set forth the nature and merits of our invention, what we claim as new 1s 1. A fanning mill provided with a drum which is hinged at one end to or upon the frame of the machine and has air-openings in each end thereof, side boards, 0, having other air-openin gs, 0, slides f 2 and c, for closing said openings, when desired, and partitions G and H, adapted to partly inclose the fan and admit air at the front side thereof, substantially as and for the purpose specified.

2. As a means for vibratingthe inner end of the lower sieve, the triangular bar R, journaled within the inner end at the lower side of the shoe, and provided with the crank-arm r, the rod S, the three-armed and perforated rocker N, the rods 0 and Q, and the perforated disk P, said parts being combined to operate substantially as and for the purpose set forth.

In testimony whereof we hereunto set our hands this 12th day of January, A. D. 1880.
